Inputs
Function Description
SYNC_IB Synchronization input for program B
(like SYNC_IA, but for program B)
SYNC_IA Synchronization input for program A
This input supports synchronization of the SPC200 with external devices (e.g.
PLC/IPC). With a Programmed Stop (command M00) the SPC200 waits for a fal
ling edge at this input before it processes the next NC record (see Fig.5/6).
STOP Stop program sequence
A falling edge at this input causes:
 the program sequence and the axes to be stopped.
 Depending on the parameterisation, the axis is stopped (controlled stop):
 The position at the time of the stop signal becomes the setpoint position

New feature
as from
OS 4.93
(default). After standstill, the axis runs back to this position.
 The current position at standstill becomes the setpoint position.
This function is only available as from firmware version 4.93 in combination
with WinPISA as from version 4.51.
If there is a 0−signal, a Program Reset can be triggered by a rising edge at
the
START input (see under ST ART input).
The program sequence is continued by:
1. a 1−signal at this input
2. a new start signal (Start on the control panel or a rising edge at the START
input).
